What are the hotkeys used in this video in Blender 2.69.1?
CTRL + A in object mode with an object selected you can apply the location, rotation, scale. CTRL + J in object mode with at least two objects selected will  join the objects to one object CTRL + V in edit with some vertices or edges or faces selected mode gives a vertices menu ALT + F in edit mode with 4 edges selected fills it with a face (beauty fill).

The hotkeys are the same for version 2.62 and 2.75 so i guess they are the some for 2.72b
